| 1. | Under Single Sign On, enter a private key that an external system can use to decrypt user IDs that it accesses through the GetUserID.ashx endpoint in the Blackbaud NetCommunity API. The external system can use the user IDs so that users who are logged in to your site do not need to enter different logins to access the external site through links on your Blackbaud NetCommunity site. |
To determine user IDs, the external system accesses the GetUserID.ashx endpoint with a return URL in the query string. The endpoint redirects website users to the return URL and uses several query string parameters to securely determine their user IDs.
